Two more stars have joined HBO's upcoming limited series "The Undoing."

Edgar Ramirez and Lily Rabe are the new additions to the project, Deadline reports. They join an already star-studded cast, led by Nicole Kidman, Hugh Grant, and Donald Sutherland.

The six-episode miniseries is written by David E. Kelley, based on Jean Hanff Korelitz's novel "You Should Have Known." He serves as showrunner, and Susanne Bier is directing. The story follows successful therapist Grace Sachs (Kidman) as her life unravels in a series of crises, including the disappearance of her husband (Grant). She then works to rebuild her life, with support from her father (Sutherland). Noah Jupe plays her young son.

Ramirez is set to play a detective named Joe Mendoza, while Rabe will play a woman named Sylvia Steinetz. He recently portrayed the victim of a crime, Gianni Versace, in Season 2 of FX's "American Crime Story." Rabe, on the other hand, stars in TNT's upcoming "Tell Me Your Secrets," and has previously starred in films such as "Miss Stevens" and "Vice."

The upcoming limited series is executive produced by Kelley via David E. Kelley Productions. Bier serves as executive producer as well, along with Kidman and Per Saari of Blossom Films and Bruna Papandrea of Made Up Stories.
